[ 1 ] - Synthesis of Tetrahydrobenzo[a]xanthene-11-one Derivatives Using ZrO2–SO3H as Highly Efficient Recyclable Nano-catalyst

The catalytic effect of Zirconia Sulfuric Acid (ZrSA) nanoparticle which is synthesized from thereaction of ZrO with chlorosulfonic acid has been investigated in the synthesis oftetrahydrobenzo[a]xanthene-11-ones by one-pot three-component reaction of β-naphthol,aromatic aldehydes, and dimedone. Different reaction conditions were studied in the presence ofZrSA nanoparticle as catalyst. The resu...
